Candle phenomenon

 

 All three above are the predictions of the processes and the outcome of the candle experiment.

Setup for the candle with my lighter
The candle was 

Setup for candle 

The candle was not because
the combustion process
makes air flow into the big tube
and CO2 out of small tube. 

Materials for candle experiment.

Candle went out fast due to
lack of air (O2) flowing into the tube.

Work done by Gases from different temperature gas inside flask and glass jar with candle falling down

From this experiment, we learned that flask. 

Device for isobaric process

Professor Mason is changing the volume slowly for this one to have a isothermal process. 

From this experiment, we learned to use the formula of W=Q=P1V1ln(V2/v1) for only isothermal systems. Furthermore the numerical answer we got -2.58J. it is negative because work is done on the system.
